Reliability-based subpacket transmission for hybrid ARQ with LDPC codes

2007 International Conference on Communications, Circuits and Systems, 2007
An irregular LDPC coded sub-packet hybrid ARQ (HARQ) scheme based on instantaneous reliability is presented for selection and retransmission. Reliability-based (RB) HARQ was initially proposed for Turbo coded case with iterative decoding, whereas for irregular LDPC coded scenario, a degree distribution based (DDB) retransmission strategy was presented ...

Subpacketization Level in Optimal Placement for Coded Caching with Nonuniform File Popularities

2019 53rd Asilomar Conference on Signals, Systems, and Computers, 2019
We consider coded caching between a server and K users and study the file subpacketization in the optimal cache placement for the coded caching scheme (CCS) with nonuniform file popularities. We formulate the cache placement optimization problem of the CCS and show the optimal cache placement has several possible structures. Analyzing these structures,

Projective Geometry based Coded Caching Schemes with Subexponential and Linear Subpacketizations

2019 19th International Symposium on Communications and Information Technologies (ISCIT), 2019
Coded Caching is a recent technique that optimizes the use of a multi-client broadcast channel by the use of local storage available at the clients and by using coded transmissions to serve multiple clients at once. While large gains in the rate of communication are obtained using coded caching, most existing schemes require that the files at the ...

Statistical Analysis of Subpacket Structure in Isolated and Overlapping Chorus Elements

Journal of Geophysical Research: Space Physics
Abstract The rising tone chorus elements exhibit fine structures composed of multiple subpackets with varying amplitudes and durations. Using Van Allen Probes data and an automated detection algorithm, we identify 834831 lower band chorus elements, classify them into isolated and overlapping types, and statistically analyze their ...
